Parts List

Schematics (3.3V FTDI Programmer)

The schematics for this project are very straight forward. You only need to establish a serial communication between your FTDI programmer and your ESP8266 to upload some code. (Repeat the schematics below for the Client and Server)

Downloading ESPlorer

I recommend using the ESPlorer program created by 4refr0nt to create and save Lua files into your ESP8266.
